  • Patent number: 7952071
    Abstract: Provided is a defect inspection apparatus and an inspection (or evaluation) method with highly improved accuracy, which would not be provided by the prior art, in the defect inspection apparatus used in a manufacturing process of a semiconductor device. Provided is a method for inspecting a sample surface with a projection type electron beam inspection apparatus, comprising the steps of: forming such an irradiation area on the sample surface by an electron beam generated from an electron gun 21 that has approximately a circular or elliptical shape of a size larger than a pattern on the sample surface; irradiating the electron beam substantially onto a center of the pattern on the sample surface; and forming an image on an electron detection plane of a detector from secondary electrons emanating from the sample surface in response to the irradiation of the electron beam for inspecting the sample surface.

  • Patent number: 7942647
    Abstract: An opening 22d of a supply/withdrawal passage 22b is positioned at the center part of the internal wall surface 22c of the operating chamber 26 (concave area 22a), and a pin 24 that protrudes toward the diaphragm 23 is provided in a position that is offset from the center of the wall surface 22c. When the diaphragm 23 is deformed toward the operating chamber 26 by the suction of an operation air into the operating chamber 26 during drawing in the chemical liquid, a part of the diaphragm 23 opposing to the pin 24 rides on the pin 24 and this part becomes a slightly convex shape toward the pump chamber 25. When the operation air is supplied from the opening 22d into the operating chamber 26 during the discharge of the chemical liquid, the deformation begins first from the part of the diaphragm 23 riding on the pin 24.

  • Patent number: 7862959
    Abstract: The present invention is a transfer mask for exposure comprising a mask portion having a plurality of cells, each of which an opening of a predetermined pattern is formed in. When one side of the plurality of cells is exposed to a charged particle beam, each of the plurality of cells is adapted to make the charged particle beam pass through itself to the other side thereof based on the pattern of the opening formed in the cell. Thus, when a substrate to be processed is arranged on the other side of the cell, the pattern of the opening formed in the cell is transferred to the substrate to be processed and hence an exposure pattern is formed on the substrate to be processed. The feature of the present invention is that a part of or all the plurality of cells can be exchanged at the mask portion.

Conductive pads (32) are formed, using an insulating material as a base, on the four side faces of a fixed member (3) having a shape that is substantially a right square prism. Magnetic field detection elements (4) are mounted on these pads (32). A cylindrical space (28) is formed in the center of the fixed member (3), and when a permanent magnet (2) fixed to a rotary member (1) is rotated in the space (28), the magnetic field detection elements (4) output signals, with a small phase error between them. A signal processing circuit (not shown) converts these output signals into angular signals.

  • Publication number: 20100144147
    Abstract: A sample holding tool is provided with a base plate, a plurality of convex portions formed on the base plate so as to stick out from the upper face thereof; and at least one holding plate having a plurality of curved face portions corresponding to the convex portions, with a lower face concave portion of each of the curved face portions being made in contact with the tip portion of each of the convex portions, so that a sample is supported on the upper face convex portion of each of the curved face portions; thus, since the sample is supported by the curved face portion of the holding plate, the contact area to the sample is made very small so that it becomes possible to greatly reduce pointed peak portions, scratches and the like at contact portions between the sample and the curved face portions. Consequently, generation of particles due to abrasion of the sample can be reduced and the particles are reduced from intruding into scratches and voids and occasionally readhering to the sample.
